Question

我创建了一个网格，现在我正在尝试从xml加载网格数据和列。我的列来自标头标签及其加载，但来自G标签的数据未加载。代码：

initComponent: function() {
    this.fields = [];
    this.columns = [];
    this.data = [];
    Ext.Ajax.request({
                        url: 'XML/hart.xml',
                        scope: this,
                        timeout: global_constants.TIMEOUT,
                        method: "GET", 
                        disableCaching: true,
                        failure: function(response) {
                            utils.showOKErrorMsg(sdisMsg.ajaxRequestFailed);
                        },
                        success: function(response) {
                            debugger;
                            var datas = response.responseXML;
                            Ext.each(datas.getElementsByTagName("HEADER"), function(header) {
                                this.buildField(header);
                                this.buildColumn(header);
                            }, this);
                            Ext.each(datas.getElementsByTagName("G"), function (columnData) {
                                this.fieldLength = this.fields.length;
                                this.record = [];
                                for (i = 0; i < this.fieldLength; i++) {
                                    this.record.push(columnData);
                                }                   
                                this.data.push(this.record);
                            }, this);
                                this.store = new Ext.data.ArrayStore({
                                    fields : this.fields
                                });
                                this.store.loadData(this.data);
                        }
                    });
    buildField: function(header) {
    this.fields.push({
        name: header.getAttribute("DATAINDEX")
    });
    buildColumn: function(header) {
    var hiddenflg = !(header.getAttribute("VISIBLE"));
    if (header.getAttribute("VISIBLE") == "false")
        hiddenflg = true;
    var strHeaderName = '';
    if ((Ext.isIE && !PC.common.isIE10()))
        strHeaderName = header.text;
    else
        strHeaderName = header.textContent;
    var strToolTip = "";
    this.columns.push({
        header: Ext.util.Format.htmlEncode(strHeaderName),
        tooltip: strToolTip,
        dataIndex: header.getAttribute("DATAINDEX"),
        width: parseInt(header.getAttribute("LENGTH")),
        metaID: header.getAttribute("M"),
        enableHdMenu: false,
        hidden: hiddenflg,
        menuDisabled: true,
        sortable: false,
        scope: this,
        /*renderer : function (value, metaData, record, rowIndex, colIndex, store){
            debugger;

        },*/
        fixed: false,
        expanded: true
    });
},
}

网格代码：在网格中我给了商店和专栏。

{xtype: 'panel',
                title: "Search Result",
                height:500,
                items: [{
                    xtype: 'grid',
                    id: 'COHART_GRID',
                    autoHeight: true,
                    selType: 'checkboxmodel',
                    frame: true,
                    store: this.store,
                    autoHeight: true,
                    stripeRows: true,
                    columns: this.columns,
                    bbar: [{
                        xtype: 'button',
                        text: 'Exclude',
                        handler: function() {
                            debugger;
                        }
                    }, {
                        xtype: 'button',
                        text: 'Include',
                        handler: function() {
                            //debugger;
                        }
                    }]
                }]

            }

如果需要，我会发布我的xml。谢谢你的帮助。

Answer 1

在buildField函数中，您正确使用getAttribute来访问属性，但在this.record.push(columnData);中您缺少它。

我认为想要一些符合

的内容

this.record = [];
for (i = 0; i < this.fieldLength; i++) {
    var fieldName = this.fields[i].name
    this.record[fieldName] = columnData.getAttribute(fieldName);
}

未经测试且没有保修，但应该是关于它的。

网格数据未从xml加载
